Abstract: A method for producing a profiled strip and the resulting profiled strip, wherein the profiled strip comprises a flexurally elastic reinforcement insert deformed, for example, into a U-shape, covered by a covering of rubber, or the like which is preferably extruded over the insert. The insert is a metal strip which is stamp cut for defining a continuous web extending across the strip and for defining at least one plurality of rungs in the metal strip. The rungs extend away from the web and preferably are defined on both opposite sides of the web. The rungs are defined by a stamp cutting operation so that after the insert is smoothed following the stamp cutting, there is no spacing between neighboring edges of adjacent rungs.

Abstract: A window frame of rubber, or the like covering material, has two U-shaped sealing strips at opposite surfaces of the window. A respective U-shaped cross-section reinforcing strip insert is embedded in each of the sealing strips. A bridge joins the legs of the two sealing strips near the window. The sealing strips and the bridge include projecting fingers which engage the window surface. The bridge is removed from the bottom of the window cutout, and the bridge instead hangs down to define guides for the sides of the window as it moves down. Each reinforcing insert is a high tensile and compressive strength metal strip, but is also flexurally elastic and is smooth on the outside and is developed approximately U-shaped in cross-section. The window frame has ends which are butted and butt vulcanized, with the butt vulcanization place being free of the reinforcement insert.
